What the developers have to say:

Why Early Access?

“Plague Inc: Evolved is in Early Access because it is currently in active development and features dangerous pathogens – so please wash your hands after playing to avoid infection!

On a serious note, it is in Early Access because the game is stable and polished but not currently feature-complete. Early Access is a great way to get player feedback on features as they are added in - helping to make Plague Inc. perfect!

Over 35 million people have played Plague Inc. to date and their input has been invaluable. Please get in touch and let me know how you want the game to evolve!”

Approximately how long will this game be in Early Access?

“We are working very hard to add in new content and cool features and hope to be out of Early Access in a few months.”

How is the full version planned to differ from the Early Access version?

“The Early Access version is stable and polished with the core game complete. The Full Version will have additional features added.

So far - we have added:

The mind controlling Neurax Worm special disease type

The zombie-making Necroa Virus special disease type

The Simian Flu from the Dawn of the Planet of the Apes movie!

18 Official Scenarios

Custom Scenario Creator

Speed run gameplay mode

3 new cheats and greatly enhanced cheat functionality

Mac support

Linux support

We are still working on:

Competitive Multiplayer mode

Co-operative Multiplayer mode

”

What is the current state of the Early Access version?

“At the moment, the game is stable and polished with the core game complete and we are working on additional features. Please only buy the game now if you are OK with this and understand that you may also encounter bugs (not the good, world-killing kind...).”

Will the game be priced differently during and after Early Access?

“We may increase the price when the game comes out of early access but this has not been decided yet”

How are you planning on involving the Community in your development process?

“Player feedback and comments are incredibly important for the development process of Plague Inc: Evolved. We are extremely grateful for having such a passionate group of players and we make sure not to take it for granted.

Players will be able to send us feedback and ideas via the steam forums, the in-game contact form, twitter, Facebook etc. We will also use polls and specific forum threads to gather targeted feedback as required.

Developer commitments:

Be open and honest with players

Clearly communicate our development plans

Always post a change log when an update is released (I hate it when this doesn't get done :P)

Read every single comment on the forums and be an active presence

Respond to every support email

Note - due to Steam Friends limit - I can't accept every friend request - sorry! I will refresh my friend list every month or so in order to talk to new people.”

During July, we have been running various technical beta tests on the multiplayer. Thank you so much to all the testers who have been sharing their findings with us - the quality of responses has been brilliant.
The headline from the beta was that the multiplayer worked without any major technical problems - this was a big relief! :)
It also provided us with a lot of connectivity data and identified a number of lobby issues as well as some lag spikes for a few players. The lobby issues are now fixed and we are putting some time into optimising data-packets to deal with the lag - initial player reports suggest it is sorted!

Although the gameplay was heavily restricted to ensure focus on the connection - we also got a few interesting gameplay facts - the most popular country to start in was China and >30% of players went with a rather powerful Nausea, Sweating, Necrosis combo! Such tactics won't have quite the same impact once the rest of the gameplay is unlocked though :P

In August, we will be beginning proper gameplay testing and also expanding the number of players in the beta. Keep an eye out for emails in case you are selected!

Unrelated to multiplayer but in the next week - we are aiming to push out a minor update to the game which contains a number of bug fixes for single player as well as adding in Korean language support. We are also working on a tutorial to help new players begin to infect the world - more details to come on that shortly!

Well done to everyone who entered the Plague Inc: Evolved "Bugs and Insects" Custom scenario competition. It's been fantastic to see so many people getting involved in the community and making enormously creative scenarios.

We had over 130 submissions, and we have played them all, (lots of them multiple times). We've seen everything from Ancient Egyptian Scarab beetles to World Wide Computer Bugs to gruesome Human Centipedes! We were really impressed with the overall standard and with so many great entries, judging the competition has been really challenging!

Anyway, what you are really interested in, is who has won. We first narrowed it down to a "long list" of possible winners (honourable mentions) and then narrowed this down to the final shortlist (Runners up). Finally, we then deliberated for quite a while about who were the three prize winners. So here are the results:

Congratulations to our winners (we'll be emailing you shortly) and thanks very much to everyone that entered, there were many more great scenarios and you should all b proud of your creations. We will be featuring everyone mentioned above at some point over the next few months.

About This Game

Plague Inc: Evolved is a unique mix of high strategy and terrifyingly realistic simulation. Your pathogen has just infected 'Patient Zero' - now you must bring about the end of human history by evolving a deadly, global Plague whilst adapting against everything humanity can do to defend itself.

10 Different Disease Types – Master every pathogen; from bacteria to bio-weapons and mind control to zombies, end humanity by any means possible – different diseases will need radically different approaches.

Infectious Multiplayer – Cooperative and Competitive gameplay; team up to fight the cure with friends, or compete in a race to kill the world.

18 Unique Scenarios – Adapt your strategy; scenarios create further challenges for your pandemic – how will you handle a new strain of Swine Flu, or infect a world in Ice Age?

Stunning Graphical Features – Watch your disease take hold; witness your pathogen mutate in real-time disease models, see humanity's struggle at street-level on city-cams, and watch the full effect of your mutations organ-by-organ on the body scanner.

Hyper-Realistic World – Strategize in the real world; advanced AI and use of real-world data and events make Plague Inc: Evolved a highly authentic simulation of a world-ending pathogen. Even the CDC likes it!

Deadly Data - Geek out with stats and graphs; monitor infection and death levels, track government reactions and cure efforts, then review your plague's success (or failure!) with full game replays.

And much more... - Including speed runs, Mega-Brutal difficulty and genetic modification... Plus loads of new disease types and scenarios in future (free!) updates.

Surprisingly, this game has a lot of replay value - The different virus types all behave slightly differently, where you start your virus from changes how the game evolves. Overtaking the world with intelligent apes would be enough to bring tears to the eyes of Jane Goodall. Each game takes roughly 30 minutes to play through (less if you decide to go with the casual option) Necroa virus is a colossal pain to get through, my zombies keep dying :(

Plague, Inc. is a smooth playing simulation strategy game that is still in the development stages, yet it already has that full-game feel. More than that, it is highly intriguing and elicits quite a few time-sensitive questions on a relevant topic today... for everyone. Whether you are concerned about Contagion, Plagues, world health, or bio-terrorism; Plague, Inc. is there. It doesn't take too many play-throughs to realize that not all diseases are created equal. But, the game does draw you to multiple play-throughs, as you spin out each scenario, captivated by the results of minor changes in your strategy. The game already includes a basic menu of disease types in the main-game portion. And, there are feature-rich simulations available as well, such as a Bubonic Plague scenario, Planet of the Apes type "Simian Flu," and myriads of others. The player is able to design and submit alternative scenarios as well. The premise is simple enough. You create a new disease and your goal is to watch it spread around the world. Naturally, since it is a game, you can't win by simply covering continents. You must wipe out humanity for a victory. You are able to name and choose the genetic traits of your disease, as well as the symptoms and the methods of spreading the disease, whether it is something that spreads from insects, birds, by air, or sea... etc. Then, as humanity fights for a cure, you try to stop the cure before you've covered the planet. What could be more exciting? Probably Plague, Inc. multiplayer. And, it's in the works as I write this review. The beta for multiplayer is coming soon, and many of us are just "dying" to get in on it.
